Reply to "What kind of freight car would you like to see next from Menards?"

The Pullman-Standard 2600 Cubic Foot Capacity 2-bay covered hopper which is much taller than the older PS-2 2003 Cubic Foot Capacity 2-bay covered hopper. This has never been made in O scale. 

Here is an example in the Detroit & Mackinac scheme. 

Other owners or operators of these covered hoppers included the Chicago & North Western, Detroit, Toledo & Ironton, Grand Trunk Western, B&O, C&O, CSX, Burlington Northern, and some other railroads.
